TQ ALL WHOM IT MAY CONCERN;

Be it known tbnt- I,'WLLIAM 1?.' C'HASE, of the city of Boston, in thecounty of Suolk, :ind Stateof Massachusetts, have inuentedcertain new:mdusetul Improvcmentsin Muehn'esffo-rv Bevelling -B'o'okbiudcrs Boards,nndsmilar articles and I do hereby declare the following to be a full,clear, and exact description oi' the same, reference being made to thedrawings accoinpenyingi'tbs s {pecification, and the iigures-nnd lettersof reference thereon. .I 'l i u l i Figure 1 of the said drawings is aview in perspective of the 1:1 1a.chine'. Figure 2 isa top' view. zFigure 3, a vertical' sectional view of the saine, tnlienthroughthe linea: az. Figure-4 is. h. perspective view of the plhne. Y Y Figure 5 is ununder side view of the sume, und Figure 6 is .u sectional view of thelatter, throu'ghthe liney y".. Similar letters of reference indicatelike parts in the several drawings.V

My invention vconsists,first, in Vthe employment of a. reciprocating plane, provided lwith an oblique c utte r, inv combinationwith anobliquegroove to guide the plane' in its truvel,wdier'eby I anx enabled to. obtein` a. smooth sheer-cut of the bookb'oardor otberiuterial; second, inthe combinution of the"adjustablc plates,V for holding thevrn:iterialfmrthe. action of the cutter, with the oblique groove undtbereciproeating cutter;

third, in the combinationfwith the oblique groove and vrecp'roczitin.gcutter, of the adjustable bed-plate, for

giving any desired bevel tothe edgeof the material fourth, in lnakingthe face of"- the plane concave, in lcorribination with en obliquecutter; -l `t h, in thecombinationn'd arrangement of the obliquegroove,the Vreiproeating. oblique cutter, andthe adjusting andholdingsplatesfull V o i' which will be fully set forth.

To enable otliersslcilled in the art (to'make and use my in vention, 'Iwill describe its construction and-mode of operation. i .l

The side pieces A A,which support the bed of the machine, are. mede withtwo cnrs, (JL-by which the 'machinecan be secured to a bench or table',and with two 1ugs,.'c, provided with .holes for the sqt-screws E E. Theadjustable plates B B :ire 4attached to the side pieces, ill-'aninclined position `the lower Vplate being stzitienhry,and tbupper oneadjustable, so thatthe aperture between them .th rough which thematerialprojects, may be adjus-tedto different thicknesses of board. 0n'these filetes, and at 4:ingle with the space between 'them ,larevplaced'the guides C C, which govern the/ movements of the plane H'.

The bed-plaiteD, on which the material is laid', is placed beneath the`plaites `Brand is capable of beingA adjusted utanydesired angle', bymeans of the screws FF, passing through the slots a a, in the-pieces A,:ind workingli holes in the project-ions@ on the underside ofthe plate..I u i llbe plane H is mede of the. desired shape, with' its face orunder surface concave, to Vprevent brasiqn of th'e material, and itscutting-ironie' sopleced atan angle with tdiaperturej-between theplatesB'B, that n sliding cr shearcutis 'inade by the plane. v

The mechine is operated s follows: The space between the plates B Bisadjusted toallow'the material to,project above theins'urfuce,byymovingthe upper plate to mj awy f rom the lower ,'plate'the necessarydis'- I tanee,' and retaining .it in'fpleec by turning `the sctfscrcwsand the bed-plcteDis' adjusted to` the anglefit is desired to give thebevel on the edge ofthe material. u .l

The book-cover or otherarticle being placed and held in position on the'bedf'plate, c clean and even bevel,l of its edge is-obtaincd byreciprocating theplane in itsvgroove alarme I claiml 1f Thereciprocating plane, provided with an oblique cutter, incombinationywith'tlle oblique groove, `to

guide the plane in its travel, whereby I qm enabledto oh'ttin a smoothshear-cut of the material, substantially as set forth and specified. i

2. The comhination, with the oblique groove and reciprocating cutter, ofthe adjustable ploteB, for holdintgr the materia'lkfor the action of thecutter, substantially :is set forth and specified. v

3. The combination', with the oblique groove and reeifnoeating cutter H,of the adjustable bed D, for givingvany desired bevel to the material,substantially. as set forth` and specified.

'4. Making the face of the cutter or plane H concave, in combinationwith the oblique cutting-iron I, whereby I obtain n clenn,-smooth cut,without abrnding the material7 substantially as specified. l

5. Thef'combination and arrangement of the oblique guides C C, thereciprocating plane II, holding-plates B Bfaind adjusting-,plate D,constructed and operating substantially :is set forth :md specified'.
